SUMMARY:PESA SA/NT May Luncheon
DESCRIPTION:PESA SA/NT May Luncheon\n“Update on Gold Hydrogen’s drilling on the Yorke Peninsula”\n Peter Bubendorfer\nGold Hydrogen\n  \nAbstract:\nGold Hydrogen was started by its founders in 2021 with applications lodged over historic hydrogen shows on Yorke Peninsula and Kangaroo Island. Applications were also lodged over areas of the Adelaide Geosyncline and Murray Basin as well as blocks on the Gawler Craton south of Whyalla. The company listed on the ASX in early 2023 and following the grant of PEL 687 has been a very active pioneering explorer. After flying airborne gravity and magnetics\, in 2023 the company twinned the original Ramsay Oil Bore hydrogen show with Ramsay 1 and 2\, intersecting up to 96% hydrogen and 37% helium\, some of the highest purities ever seen in underground wells. Post drilling\, a 2D seismic survey was carried out and at the end of 2025 two further wells were drilled which confirmed continuity of reservoir. The company is preparing to flow test its wells later this year. \n  \nEvent Details:\nThursday\, 28th May 2026 \nLuncheon: 12 pm for a 12:30 pm start \nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nThe luncheon will consist of 2 courses and drinks \nBookings close 5 pm Monday\, 25th May  2026 \nAny late bookings will incur an additional $20 fee. Strictly no walk-ins.

SUMMARY:PESA SA/NT April Luncheon- Cooper Basin - seismic processing & where it leads ...
DESCRIPTION:PESA SA/NT April Luncheon\nJoint meeting with ASEG SA-NT\nCooper Basin – seismic processing & where it leads …\nPeter Strauss\n  \nAbstract:\nProcessing and interpretation work on the Western Flank of the Cooper Basin indicate that modern land 3D seismic datasets are often not fit-for-purpose when targeting smaller-scale structures. One of the primary objective in this region\, the Namur horizon\, is typically a strong and easily identifiable seismic event. Exploration success therefore depends less on horizon picking and more on accurately positioning wells on genuine structural highs. However\, deeper targets beneath the Namur present greater challenges. In these intervals\, seismic events are often discontinuous and geologically inconsistent\, making both structural interpretation and imaging problematic. \nThis talk highlights two key issues: \nThe structural problem is not new—it was identified in 2D seismic data approximately 30 years ago\, where structural “corrections” were applied. These corrections have not been consistently carried through into modern 3D datasets.\nImaging quality in onshore seismic data is being compromised by the application of processing workflows originally developed for marine 3D seismic. These methods are poorly suited to land data\, where targets are significantly smaller and geological complexity is higher. Avoiding such approaches can yield sharper\, more geologically meaningful seismic images better suited to land exploration. \nEvent Details:\nThursday\, 30th April 2026 \nLuncheon: 12 pm for a 12:30 pm start \nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nThe luncheon will consist of 2 courses and drinks \nBookings close 5 pm Monday\, 27th April 2026 \nAny late bookings will incur an additional $20 fee. Strictly no walk-ins.

SUMMARY:PESA SA/NT: Barry Goldstein Medal Lecture Tour Feb 2026 - Bruce Ainsworth
DESCRIPTION:PESA SA/NT February Luncheon\n“Honouring the Humble Clinoform: Towards a Reservoir Modelling Best Practice”\nBruce Ainsworth\nPESA Barry Goldstein Medal Lecture Tour 2026\nSponsored by Santos\n  \nAbstract:\nClinoforms have fascinated Bruce since first pondering their economic significance in Shell Research Laboratories in the early 1990’s. These dipping stratal surfaces are ubiquitous in the stratigraphic record but often ignored with regard to their potential significant influence on fluid flow in the subsurface. Whether you are interested in hydrocarbon or groundwater extraction\, carbon sequestration\, or sediment hosted uranium\, you need to know if you are dealing with clinoforms. Clinoforms can have significant impacts on resource recovery and emplacement. Ignoring them or simply not recognising them can have profound (usually) negative impacts on project value. Key to making clinoforms your best friend are three steps; 1) recognition\, 2) uncertainty management\, and 3) targetted modelling. This talk will guide the clinoform user through these steps and suggest a reservoir modelling best practice for honouring the humble clinoform. \nEvent Details:\nThursday\, 26th Feb 2026 \nLuncheon: 12 pm for a 12:30 pm start \nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nThe luncheon will consist of 2 courses and drinks \nBookings close 5 pm Monday\, 23rd Feb 2026 \nAny late bookings will incur an additional $20 fee.

SUMMARY:PESA SA/NT Annual General Meeting & Christmas Luncheon 2025
DESCRIPTION:PESA SA/NT\nAnnual General Meeting & Christmas Luncheon\n\nDate: Thursday\, 11 December 2025\, Time: 12:30 PM\nVenue: Ayers House\, North Terrace\, Adelaide\n  \nAnnual General Meeting \nThe PESA South Australia/Northern Territory Branch invites all members to attend the 2025 Annual General Meeting (preceding the Christmas Luncheon) .This important event provides a valuable opportunity to reflect on the year’s progress\, recognize our collective achievements\, and plan for the year ahead. \nThe AGM will be held immediately prior to the PESA SA/NT Christmas Luncheon\, offering members the chance to engage in both professional discussion and seasonal celebration. \nAgenda \n\nPresident’s Report – Review of the Branch’s activities and milestones accomplished throughout 2025.\n\nTreasurer’s Report – Presentation of the financial summary and key fiscal updates. \n\n\nProposed 2026 Committee – Introduction of the nominated committee members for the upcoming year. \n\n\nAdditional Nominations from the Floor – Opportunity for further nominations to be put forward. \n\n\nAny Other Business (AOB) – Open discussion of other matters of interest to members. \n\n\nAll members are encouraged to attend\, contribute to the discussions\, and participate in the formation of the 2026 committee. Your engagement helps guide the direction of our Branch and ensures that our community continues to thrive. \n  \nChristmas Luncheon\nChristmas Geo-Crackers with David Grybowski\n\n  \nAbstract: \nBorn 29 May 2006 and not dead yet. Volcanoes are no strangers to Indonesia and Lusi is the ……………………………………………………………..wisdom in this thrilling Christmas luncheon. \nOops sorry! Wrong talk. A Christmas lunch is a time to have a few laughs\, and when you dig deep into the Lusi disaster\, it deserves our serious consideration later in the year.   \n For your entertainment\, David will instead present a trio of Christmas crackers.  \n\n Why Does The Niagara Fall?\n\n Forbes has Niagara Falls in second on their bucket list of travel destinations – wedged in between the Maldives and the Mona Lisa. But what is the geology over which the Niagara falls? Newlywed couples don’t care. Nobody is curious enough to ask this question except the Petroleum Exploration Society of Australia’s SA/NT branch. Once again\, David Grybowski will give you all the answers you’ve been yearning for.  \n\n Petroleum Dreaming of the Adelaide Plains \n\n In a short presentation\, David will geo-fantasise the petroleum reservoir targets present in the geomorphology of the Adelaide Plains as if they were depositional environments under a seal of transgressive mudstones and thousands of metres of overburden.   \n\n The Ancient Turkish Coast \n\n Time permitting\, David will reprise part of his Cry Me A River presentation that he gave in 2022 about the fluvial filling of the River Meander in western Turkey that left ancient ports stranded from the sea.  \n\n And a sneak preview of Lusi – The Greatest Mud Volcano Disaster in the World. \n\nA thrilling Whatdunnit and Who-pay-for-it.  \n  \nDavid returns to the PESA podium with another Christmas cracker-good pole axing of industry norms. October 2022 saw fluvial hi jinks with Cry Me A River and the world premiere of the petroleum play pitch The Project – A Play About Not Working Together.  For the Christmas luncheon of 2023\, David shared his rock-starred childhood with The Books That Hooked Me – an investigation of the childhood books and collectables that turned his head toward geology. David then revealed his interest in engineering with The Role of Toilet Paper; a descriptive tour de force of public paper dispensers we all love to hate. David’s 35 years in petroleum geology has given him ample opportunity to ponder where things might have gone wrong. Most of his experience was with Santos. \n Tickets for the luncheon: \n\n\n\nMembers $80.00\nNon-Members $120\nStudents $30.00\n\n\n\n\nEvent Details:\nThursday 11 December 2025 \nLuncheon: 12 pm for a 12:30 pm start \nThe luncheon will consist of 3 courses and a 3-hour drinks package \nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nBookings close at 5 pm Monday\, 8th December 2025 \nAny late bookings will incur an additional $20 fee.

SUMMARY:PESA SA/NT November Luncheon : Moomba CCS
DESCRIPTION:PESA SA/NT  November Luncheon\nMoomba CCS – delivering a world leading CO2 storage project\nAnthony Western (Santos)\n  \nAbstract:\nThe Moomba Carbon Capture and Storage project is a large-scale CCS project at the Moomba Gas Plant in the Cooper Basin\, South Australia. New facilities were constructed to capture\, dehydrate\, transport and permanently store CO2 emissions that were previously vented to atmosphere and depleted gas fields were selected as the initial storage reservoirs. Five new injection wells were drilled\, and existing wells were re-purposed as monitoring wells to enable the Monitoring and Verification (M&V) plan including environmental assurance monitoring. \nThe Moomba CCS project commenced operations in September 2024 and by June 2025 had safely captured and permanently stored more than 1.0 million tonnes of CO2 emissions. The wells and storage reservoir are performing as expected and monitoring wells are seeing signs of CO2 injection in line with reservoir model predictions. At 1.7 Mtpa CO2e\, it is one of the largest CCS projects in the world and its successful startup and early performance has enabled future CCS growth in the Cooper Basin. \nThis presentation will give an overview of the Moomba CCS project and share some of the results to date\, with a focus on subsurface scope. \n\nEvent Details:\nThursday 20th November 2025 \nLuncheon: 12 pm for a 12:30 pm start \nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nThe luncheon will consist of 2 courses and drinks \nBookings close 5 pm Monday\, 17th Nov 2025 \nAny late bookings will incur an additional $20 fee. Strictly no walk-ins.

SUMMARY:PESA SA/NT November Luncheon : PESA Distinguished Lecturer
DESCRIPTION:PESA SA/NT  November Luncheon\nRecent applications of seismic geomorphology/stratigraphy: Deep-water deposits of the Bay of Bengal and the Norwegian Sea\nHenry Posamentier\n(PESA Distinguished Lecturer)\n  \nAbstract:\nThis presentation will document the seismic stratigraphic and seismic geomorphologic expressions of deep-water deposits of the Bay of Bengal and the Norwegian Sea. They comprise both turbidites as well as mass transport deposits. The turbidite deposits from the Bay of Bengal include leveed channel complexes\, terminal fans\, and overbank sediment waves. With respect to terminal fans\, there are those that terminate basinward of leveed channel systems and are relatively large\, and those that are deposited late within a lowstand cycle of deposition and are confined between the levees of precursor larger channels\, and are relatively small. Intra-basinal channels (i.e.\, channels that start and end on the basin floor) are observed within abandoned meander loops as well as interchannel overbank terrains. These intra-basinal channels are characterized by low sinuosity and likely are mud-filled with no exploration potential. \nMass transport deposits from the Norwegian Sea include flows\, slumps\, and slides\, as well as isolated outrunner blocks. These deposits are associated with significant substate erosion up to 250m. The outrunner blocks are observed in clusters\, generally in radiating patterns down-system. Some of the outrunner blocks at the termini of erosional furrows are associated with sediment tails orthogonal to the direction of transport\, indicating bottom current direction from southwest to northeast. In addition\, volcanic intrusive deposits will be documented. These intrusives comprise both dikes and sills. Some of the dikes are associated with laccoliths in the shallower section. \nThis PESA Distinguished Lecture is made possible with the generous support of Santos Ltd. \nEvent Details:\nDate: Monday 3rd November 2025 \nBookings close 5 pm Wednesday\, 29th Oct 2025 \nLuncheon: 12 pm for a 12:30 pm start . The luncheon will consist of 2 courses and drinks \nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nCost: Training Course ( Seismic Geomorphology and Seismic Stratigraphy – Fundamentals and Workflows) Attendees Free\, Members $ 60\,  Non-Members $ 75\,  Students $25. \nAny late bookings will incur an additional $20 fee.

SUMMARY:PESA SA/NT Evening Technical Talk: Three-Dimensional Architecture of Wave-Dominated Delta Deposits
DESCRIPTION:PESA SA : Evening Technical Talk\nThree-Dimensional Architecture of Wave-Dominated Delta Deposits\nBrian Willis1\, Tao Sun2 and Bruce Ainsworth3\n  \n1. Presenter\, Willis Geoscience\, Consultant\, Longmont\, CO\, USA; 2. Chevron Technology Center\, Research Fellow\, Houston\, TX\, USA; 3. Adjunct Professor\, University of Adelaide\, Australia. \nSep. 29th 2025\n  \nJoin PESA SA/NT for an Exclusive Distinguished Lecturer Event Featuring Brian Willis \nPESA SA/NT is proud to host Brian Willis\, renowned fluvial sedimentologist and stratigrapher with decades of experience at Chevron and BP\, as part of our Distinguished Lecturer Tour. This PESA Distinguished Lecture is made possible with the generous support of Santos Ltd. \nOverview:\nNew numerical wave-influenced delta depositional models are challenging long-held rational for interpreting sea level variations recorded by wave-dominated shallow-marine successions. Shallow-marine\, wave-dominated deposits (parasequences) are generally inferred to exhibit a decrease in wave energy and grain size with increasing water depth and to occur in facies belts that are laterally continuous for long distances along strike. Bedding geometry and vertical facies successions within these parasequences are interpreted in relation to a prograding equilibrium shoreface profile (cf. Bruun rule) and a gradual upward-coarsening facies progression (cf. Walther’s law). Sea-level fall is commonly inferred to generate a sharp-based shoreface succession\, characterized by an abrupt vertical transition from heterolithic lower shoreface to sandy upper shoreface deposits across a marine erosion surface. A truncated vertical shoreface succession\, capped by a marine erosion surface\, is inferred to record significant wave ravinement during sea level rise and transgression. \nThree-dimensional\, process-physics-based\, coupled hydrodynamic-morphodynamic wave-influenced delta models suggest that wave-dominated deltas will develop a sandy shoreface inner clinoform dipping from the subaerial delta plain to a relatively flat wave-scoured subaqueous delta top\, which is laterally separated from a muddier delta front outer clinoform that dips from the subaqueous delta top edge to the shelf floor. As these systems prograde\, deposits of these dual-clinoforms will become vertically stacked and will be separated by a regressive surface of marine erosion formed on the subaqueous delta top. Grain-size contrasts between these vertically stacked clinoform deposits reflect differences in sediment-transport directions and sorting under river- and wave-driven littoral currents along the coast\, and cannot be uniquely related to sea-level changes. Gradual vertical facies successions develop where waves are less effective at reworking river-supplied sediment alongshore. In contrast\, sharp-based shoreface deposits record more effective wave separation of sands onto the shoreface clinoform as muds are preferentially transported offshore onto the subaqueous delta clinoform. \nThe continuity of a regressive surface of marine erosion over many tens to hundreds of kilometres across mid-shelf regions of some stratigraphic sequences reflects a gradual lateral shift in the position of littoral current erosion on a subaqueous delta top. Timelines cross such vertical lithic discontinuities throughout the extent of a prograding deposit\, and the regressive surface of marine erosion thus has little chronostratigraphic significance. The model results are used to suggest: 1) Characteristic strongly asymmetric wave-dominated parasequences suggest common river avulsion at the start of transgression\, 2) Observed down-dip transitions from “gradual-based” to “sharp-based” shoreface deposits might record reduced sediment supply to the coast relative to rates of longshore drift as the system expands toward its auto-retreat limit\, rather than transitions from normal to forced regression\, and 3) Regional “top-truncated” shoreface successions might record progradation of dual-clinoform shorelines with wide deviation in net direction of regional sediment supply and shallow-water wave transport\, rather than significant regional transgressive ravinement. The results of these models suggest caution in inferring sea-level changes from the character of vertical facies changes observed in individual well logs and isolated outcrop exposures. The models suggest new facies relationships that require testing in modern systems\, outcrops\, and subsurface examples. \n  \n  \nTimings for the event: \n5:30 to 6:00 – pre-talk drinks and canapes\n6:00 to 7:00 – evening talk and Q&A\n7:00 to 7:30 – post-talk drinks in the bar \nPESA SA/NT will provide a selection of canapes.

SUMMARY:PESA SA : Meandering Murray Field Trip & Fluvial Stratigraphy Workshop
DESCRIPTION:PESA SA : Meandering Murray Field Trip & Fluvial Stratigraphy Workshop\nMagnificent Meandering Murray field trip: a modern-day fluvial system analogue\nSep. 28th and 29th 2025\nBrian Willis (ex Chevron ) & Andrew McKerron (Beach Energy)\n  \nJoin PESA SA/NT for an Exclusive Distinguished Lecturer Event Featuring Brian Willis \nPESA SA/NT is proud to host Brian Willis\, renowned fluvial sedimentologist and stratigrapher with decades of experience at Chevron and BP\, as part of our Distinguished Lecturer Tour. This PESA Distinguished Lecture is made possible with the generous support of Santos Ltd. \n  \nThis exciting two-day workshop offers a unique blend of field and classroom learning: \n  \n\nDay 1: Field Excursion – Sunday\, 28 September Explore the stunning landscapes of the Murray River on a guided geological field trip led by Brian Willis and Andrew McKerron\n\n          Ticket Price: Free to attend | Logistics (Self organized) meeting point will be advised closer to the date \n  \n\nDay 2: Fluvial Reservoir Heterogeneity Characterization Workshop – Monday\, 29 September \n\n         Ticket Price: $250 per participant | Location: Ayers House \nWhether you’re a student\, professional\, or enthusiast\, this is a rare opportunity to learn directly from one of the industry’s leading experts. \nLimited spots available – register now! \n  \nWorkshop Details:\nFluvial Systems – From River to Reservoir\nTraditional characterization of fluvial reservoirs focuses on relating vertical facies patterns observed in core samples to a static aerial view of an analogue river. Such comparisons fall short of generating precise predictions of the distribution of reservoir heterogeneities that can impact subsurface fluid flow and reservoir development behavior. Heterogeneity patterns within fluvial deposits are emergent structures (i.e.\, in systems analysis\, “emergent structures” are patterns that arise from the collective actions of many individual parts and behaviors and have properties that the parts themselves do not have). In fluvial deposits\, these patterns are formed by shifts in deposition and erosion during river floods\, dynamic changes in grain sorting along a river channel during lateral migration and cutoff within a channel belt\, and the stacking of channel belts as the floodplain aggrades. This course aims to build on traditional fluvial facies models to develop a more dynamic understanding of how a hierarchy of depositional processes defines heterogeneity patterns within fluvial reservoirs. \n• Discuss terminology and concepts to define the hierarchy of processes and deposits that control reservoir-heterogeneity 3D patterns and scaling. \n• Examine process-based\, numerical\, river depositional models to better understand the emergence of heterogeneities within evolving channel belts. \n• Catalogue 3D facies patterns developed within a range of river systems as a template for defining reservoir heterogeneity. \nLectures will introduce the hierarchical organization of fluvial deposits and discuss models for the development of heterogeneities within fluvial channel belts. The focus is on considering how dynamic changes preserve 3D facies patterns and understanding how these facies patterns vary between a wide range of fluvial systems. Well log interpretation and correlation exercises will demonstrate subsurface applications. The workshop is structured to challenge experienced practitioners to rethink standard practices\, while remaining general enough to benefit geologists with little experience in fluvial systems\, as well as reservoir modelers and engineers\, with a broad overview of potential subsurface variation patterns. \n  \nWorkshop Timing: \n9:30 am-5:00 pm \n  \nBrian Willis will be giving an evening talk at 5:30 pm. The talk is free for workshop attendees\, but registration is required.

In order to address these challenges\, we developed two novel in-situ laser-based methods that have the potential to quickly and accurately resolve these processes. The first method provides a tool to date clay phases in shales using Rb–Sr geochronology. We show that the Rb–Sr isotopic system in shales is sensitive to temperatures equivalent to the oil-gas window. The second technique demonstrates an approach for dating carbonate formation using U–Pb geochronology via a laser isotopic mapping approach. The laser rasters can be compiled into interactive maps\, and this spatial and geochemical information can be used target multiple generations of carbonate mineralisation. Records of natural carbonate precipitation can be used as an analogue for assessing the potential of host rocks for carbon capture and storage.\n\nEvent Details:\nThursday 28th August 2025 \nLuncheon: 12 pm for a 12:30 pm start \nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nThe luncheon will consist of 2 courses and drinks \nBookings close 5 pm Monday\, 25th August 2025 \nAny late bookings will incur an additional $20 fee.

SUMMARY:PESA SA/NT July Luncheon
DESCRIPTION:PESA SA/NT July Luncheon\nNew Geological Studies Leading to 2025 Acreage Release in the Polda and Otway Basins\, SA\nPaul Strong and Sharon Tiainen \n(Energy Resources\, Geological Survey of SA\, Department for Energy and Mining)\nThe Polda Basin is a 10\,000 km2 Neoproterozoic to Jurassic basin covering the central western portion of the Eyre Peninsula of South Australia and extends westwards into the Great Australian Bight. The basin is only lightly explored\, with the last significant hydrocarbon exploration occurring in the offshore Polda Basin in the late 1970s/early 1980s\, with no reported hydrocarbon shows except for a relatively minor gas show of 40 ppm methane in Mercury 1. However\, source rock studies in the Jurassic section indicate the presence of immature\, relatively high TOC and excellent generative potential for both oil and gas from carbonaceous claystone and coal. Recent work by the GSSA (Tiainen\, 2025) indicates the presence of a potential source rock from the underlying Neoproterozoic Kilroo Formation\, with oil staining identified in the permeable reservoir intervals in the Polda Formation in the onshore mineral drillhole Kilroo 1A. In addition\, recent work conducted at the University of Adelaide suggests that there may be potential for a natural hydrogen accumulation within the onshore Polda Basin (Rumi Daruso 2023\, shown in Margiono et al. 2024). \nFollowing a recent acreage relinquishment\, one new Regulated Substances Exploration Licence (RSEL) in the Polda Basin is being offered as acreage release block PO2025 RSEL-A by the South Australian Government for competitive work program bidding. \nThe Otway Basin is one of the best known and most actively explored of the series of Mesozoic rift basins that span the southern coastline of Australia\, formed following rifting between the Antarctic and Australian plates. Over the last 2 years DEM has conducted studies over most of the onshore Otway Basin in South Australia\, with results suggesting that significant hydrocarbons have been generated and expelled in a number of structural troughs in the region\, and that suitable reservoir fairways and new play types are now better defined than previously. \nFollowing a recent acreage relinquishment\, five new regulated substances exploration licences (RSELs)\, three gas storage exploration licences (GSELs) and one new geothermal exploration licence (GEL) in the Otway Basin are being offered by the South Australian Government based on work program bidding. A key motivation for the acreage release is the looming shortfall in energy supply in the southeast Australian market. The South Australian onshore Otway Basin is in a strategic location for natural gas exploration and gas storage. \n  \n  \n\nEvent Details:\nThursday 31st July 2025\nLuncheon: 12 pm for a 12:30 pm start\nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nThe luncheon will consist of 2 courses and drinks \nBookings close 5 pm Monday\, 28th July 2025 \nAny late bookings will incur an additional $20 fee.

SUMMARY:PESA SA/NT June Luncheon
DESCRIPTION:PESA SA/NT June Luncheon\nThe impact of triggered earthquakes of the Basel geothermal project 2006 on Engineered Geothermal Systems\nMarkus Häring (Consultant)\nThe triggered earthquake of M 3.4 with subsequent events of M >2 was a turning point in the perception of induced seismicity caused by intentional pressure changes in the subsurface. The events followed a massive hydraulic stimulation into granitic basement at 5 km depth below the city of Basel. \nThe geothermal project attracted worldwide attention\, not only because the seismicity was felt throughout the city\, but also because\, for the first time\, induced seismicity was recorded in detail by a scientifically supported monitoring system. \nSince then\, microseismic monitoring systems have been greatly improved and can now be used in all underground operations where pressure changes occur\, such as oil and gas production\, fraccing\, CCS and EGS. \n  \n  \n\nEvent Details:\nThursday 26th June 2025\nLuncheon: 12 pm for a 12:30 pm start\nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nThe luncheon will consist of 2 courses and drinks \nBookings close 5 pm Monday\, 23rd June 2025 \nAny late bookings will incur an additional $20 fee.

SUMMARY:PESA SA/NT May Luncheon
DESCRIPTION:PESA SA/NT May Luncheon\nProspectivity of the Daralingie Shelf area of the Warburton Basin\, SA\nTim Rady (Geomorph Energy) and Rob Kirk (Consultant)\nAbstract:\nTo further highlight the prospectivity of the Warburton Basin\, the South Australian Department for Energy and Mining (SADEM) has undertaken a whole of basin project integrating regional seismic interpretations (using the 2D Cube)\, previous geological understanding\, well and standardized core interpretations. The May 2025 PESA lunch will be the first public release of the main outcomes from this project. \nThe Cambrian eastern Warburton Basin underlies the bulk of the hydrocarbon-producing Permian Cooper Basin in South Australia. The Warburton\, like the Cooper Basin\, is hydrocarbon bearing with a significant catalogue of hydrocarbon shows recorded from a wide variety of lithologies and stratigraphic intervals. Therefore\, understanding the stratigraphic context of hydrocarbon occurrences is critical to unlocking this basin’s prospectivity. It is in this context that two integrated seismic-based interpretations were undertaken in this project and are the focus of PESA’s May 2025 lunch time lecture. \nThe initial seismic interpretation\, by R. Kirk\, looked at the whole eastern Warburton Basin with the results providing the stratigraphic and gross depositional environment (GDE) concepts that underpin the entire project. From this work a new stratigraphic sub-division of the Warburton Basin has been developed (Kirk et al 2025). Subsequently\, the second seismic study was undertaken (by T. Rady) building upon the seismic sequence stratigraphic framework developed by Kirk et al (2025) by combining seismic attributes\, structural and seismic facies mapping and core descriptions to develop GDE and updated reservoir distribution maps for the uppermost section\, termed ‘400-1000’. This work has provided new insights into the basin stratigraphy\, evolution and prospectivity for hydrocarbons (Rady et al 2025). \n  \n\nEvent Details:\nThursday 22nd May 2025\nThe May luncheon is a week earlier than usual due to the AEP conference during the last week of May \nLuncheon: 12 pm for a 12:30 pm start\nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nThe luncheon will consist of 2 courses and drinks \nBookings close 5 pm Monday\, 19th May 2025 \nAny late bookings will incur an additional $20 fee.

SUMMARY:PESA SA/NT March Luncheon
DESCRIPTION:PESA SA/NT March Luncheon\nThe Perth Basin: Seven years of learnings\nAndrew Farley (Strike Energy)\n  \nAbstract:\nExploration in the Perth Basin commenced back in the 1960s\, but it was the discovery of the Kingia gas play by AWE Energy in 2014 that kicked off the latest round of exploration and development. The Waitsia gas discovery inspired Strike Energy to enter the basin in 2018 with success at West Erregulla 2 in 2019 proving that porosity and permeability continues to preserved despite greater depth. To date\, Strike has drilled 13 deep wells and acquired 6 new seismic surveys across the Permian Kingia and Jurassic Cadda/Cattamarra plays. This has led to the discovery of 4 new gas fields\, one of which is now on production\, and two which are being developed. \n  \n\nEvent Details:\nThursday 27th March 2025\nLuncheon: 12 pm for a 12:30 pm start\nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nThe luncheon will consist of 2 courses and drinks \nBookings close 5 pm Monday\, 24th March 2025 \nAny late bookings will incur an additional $20 fee.

SUMMARY:PESA SA/NT February Luncheon
DESCRIPTION:PESA SA/NT February Luncheon\nSeismic interpretation of the Petrel Sub-basin CO2 Storage Opportunity \nJames Komenza\nAbstract: \nAn integrated geologic and geophysical study of the Mesozoic storage resource in the Petrel Sub-basin (Bonaparte Basin). This study includes regional petrophysics\, geomechanics\, rock physics\, seismic reprocessing and inversion in an area of sparse well and seismic data. \nAlthough numerous wells have been drilled in the Petrel Sub-basin\, their focus has been the underlying Palaeozoic petroleum system\, resulting in scant or compromised data quality in the overburden. This often limits data utility for reservoir characterization\, field appraisal and development planning for the primary Mesozoic storage targets. Seismic reprocessing and quantitative interpretation supported by a model-based rock physics workflow have been used to fill in some of the gaps. This new data has been used to interpret depositional trends of both reservoir and seal\, reservoir quality\, heterogeneity and clay content\, seal presence and thickness\, and interval velocity away from well control. Insights from this study further highlight the suitability of G-11-AP for large scale CO2 storage. \n  \n\nEvent Details:\nThursday 27ht February 2025\nLuncheon: 12 pm for a 12:30 pm start\nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nThe luncheon will consist of 3 courses and a 3-hour drinks package \nBookings close 1 pm Monday\, 24th February 2025 \nAny late bookings will incur an additional $20 fee.

SUMMARY:PESA SA/NT Christmas luncheon
DESCRIPTION:PESA SA/NT Christmas luncheon\nAnnus Mirabilis\nThe breakthrough year when petroleum geoscience changed forever\nRhodri Johns\n  \nAbstract: \nIn a single remarkable year\, several key papers and books were published that revolutionised the petroleum geosciences. \nSome of these publications introduced groundbreaking ideas\, concepts\, and methodologies that stunned and astonished both academia and the petroleum industry. Others synthesised state of the art in disciplines such as sedimentology and geochemistry\, building on developments from the previous decades\, like pieces of a jigsaw puzzle falling into place; these works not only led to a more innovative approach to petroleum exploration but also laid the foundations for systematic basin analysis\, play analysis\, petroleum systems analysis\, and risk analysis – approaches that would emerge as essential tools for the petroleum industry in the 1980/90s and beyond. \nWhat were these pivotal publications\, and who were their authors? How and where did these ideas and breakthroughs originate\, and how were they received by both academia and the industry? \nRhodri Johns will tell this story from a personal perspective\, offering new insights from those closer to the action. \n  \n\nEvent Details:\nThursday 12 December 2024\nLuncheon: 12 pm for a 12:30 pm start\nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nThe luncheon will consist of 3 courses and a 3-hour drinks package \nBookings close 1 pm Monday\, 9th December 2024 \nAny late bookings will incur an additional $20 fee.

SUMMARY:PESA SA/NT November Luncheon: Natural Hydrogen Exploration in South Australia: An Update
DESCRIPTION:Natural Hydrogen Exploration in South Australia: \nAn Update\nChris Cubitt \nGeological Survey of South Australia\, Department for Energy and Mining \nhttp://www.energymining.sa.gov.au/ \nchris.cubitt@sa.gov.au \n  \nAbstract: \nSouth Australia took the lead nationally in enabling exploration licences for natural hydrogen on 11 February 2021 when amendments to the?Petroleum and Geothermal Energy Regulations 2013?declared hydrogen\, hydrogen compounds and by-products from hydrogen production ?regulated substances?. Following on from this\, seven companies have lodged over 40 applications for PELs targeting natural hydrogen over the State?s basins and crystalline basement provinces. PEL 687 is the first licence in Australia targeting natural hydrogen and was granted to first movers Gold Hydrogen Pty Ltd in July 2021 over Yorke Peninsula and Kangaroo Island. The second licence (PEL 691) was granted to H2EX in June 2022 over eastern Eyre Peninsula. An update will be given with respect to current exploration activities in both active licences and with reference to the current understanding of natural hydrogen prospectivity across South Australia. \n\nEvent Details:\nThursday 28th November 2024\nLuncheon: 12 pm for a 12:30 pm start \nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nIncludes a 2-course lunch and drinks \nBookings close 1 pm Monday\, 25th November 2024 \nAny late bookings will incur an additional $20 fee.

SUMMARY:PESA SA/NT Branch October Luncheon
DESCRIPTION:An emerging new Petroleum System with world-class plays in the \nTorres Sub-Basin\, Offshore Papua New Guinea \nTim Rady1 and John Chambers2  \n1 Geomorph Energy \n2Larus Energy Limited \n\nABSTRACT\nThe Papuan Basin is the only basin with production in Papua New Guinea but is relatively unexplored for a typical Australian Continental Margin Mesozoic basin. It hosts the Kutubu Oil Field Developments and the PNG LNG project\, as well as several gas fields that are planned to be developed in the coming years\, but its southeastern extension\, the Torres Sub-Basin\, remains undrilled. Modern proprietary and regional multi-client seismic data in the offshore Torres Sub-Basin is now revealing an active Petroleum system with a generating Late Cretaceous Source rock and three main identified play types: \n\nMiocene deep-water clastics in a large submarine Miocene to Pliocene foldbelt\nPinch-out plays of Miocene to Pliocene age against a basement high\nPalaeogene carbonate build-ups on basement highs\n\nThis presentation will focus on the Miocene to Pliocene submarine foldbelt plays within the Larus Energy-operated PPL579 license area that was covered by the Nanamarope 3D broadband PSDM seismic survey (acquired in 2023 by Larus Energy and Searcher). The pinch-out play is within the recently awarded Larus Energy-operated PPL695 license in the foreland basin south of the foldbelt\, while TotalEnergies is proposing to test the Palaeogene carbonate play with the Mailu-1 well in 2025. \nThe Nanamarope 3D seismic provides high-resolution images of large-scale submarine fan complexes\, deposited during the Mid-Miocene\, linked to active tectonism and the formation of the proto–Owen Stanley Range. The images suggest significant reworking of these turbidite systems by bottom currents into likely high reservoir quality contourite deposits with a wide spectrum of features formed during synchronous and asynchronous interaction of turbidity flows and bottom current activity. It is observed that bottom currents provide a mechanism to redistribute coarser-grained material up-slope and beyond the limits of the traditional turbidite fairway. \nThe new 3D seismic has allowed Larus to complete detailed structural mapping\, update GDE interpretations\, identify evidence for hydrocarbon migration and integrate petroleum systems and seismic synthetic forward modelling to derisk the prospectivity. Larus Energy is planning on drilling the giant Nanamarope Prospect in 2025 which\, if successful\, will open a large new play fairway for exploration and development and provide a much-needed revenue source for the nation of Papua New Guinea \n\nEvent Details:\nThursday\, 24 October 2024\nLuncheon: 12 pm for a 12:30 pm start \nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nIncludes a 2-course lunch and drinks \nBookings close 1 pm Monday\, 21st October 2024 \nAny late bookings will incur an additional $20 fee.

SUMMARY:PESA SA/NT Branch September Luncheon- 26 September
DESCRIPTION:Salt Cavern storage potential of the Polda Basin\, South Australia\nGlenn Toogood\, entX\, and Tim Rady\, Geomorph Energy\n\nThe Polda Basin is a Neoproterozoic to Jurassic sedimentary basin\, extending from the Great Australian Bight to the central Eyre Peninsula\, South Australia. It has previously been explored for petroleum\, uranium\, coal\, groundwater\, base metals\, potash and diamonds. There has been renewed interest in the Polda Basin for its underground gas storage potential in salt caverns\, given that Mercury-1 encountered >1200m of massive halite within Neoproterozoic red beds in the central offshore basin.\nentX Limited were granted Gas Storage Exploration Licences (GSEL) 781 and 784 and have been actively studying the basin to assess the likelihood of the proven offshore salt extending onshore\, where it may be engineered into caverns for underground gas storage (UGS) sites. UGS can provide gigawatt-scale storage of H2 gas and significantly reduce the levelized cost of storage. Such an asset would provide key advantages to H2 project concepts\, including DRI green steel from magnetite\, green ammonia and biofuels.\nTo assess the prospectivity for salt onshore and correlate the stratigraphy across the basin\, entX have taken a multi-disciplinary approach\, reviewing all available data and literature and integrating seismic reprocessing\, ICP-MS/OES and XRF analysis\, visual core and cuttings interpretation\, core density measurements\, spectral scanning and gravity forward modelling. Following this work\, the onshore Polda Basin has emerged as highly prospective for both salt and natural hydrogen. This talk will summarise the technical work undertaken\, new insights about the stratigraphy and plans for future data acquisition.\n\nEvent Details:\nThursday\, 26 September 2024\nLuncheon: 12 pm for a 12:30 pm start \nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nIncludes a 2-course lunch and drinks \nBookings close 1 pm Monday\, 23rd September 2024 \nAny late bookings will incur an additional $20 fee. Strictly no walk-ins.

SUMMARY:PESA SA/NT Branch August Luncheon- Thursday 15
DESCRIPTION:2024 Birdsall-Dreiss Distinguished Lecturer\nDr. Ben Rostron\nProfessor Emeritus of Earth & Atmospheric Sciences at the University of Alberta\n\nAbstract:\nGeology and hydrogeology at AQUISTORE: Canada’s first CO2 storage project associated with a commercial-scale coal-fired power plant The Aquistore research project is part of SaskPower’s Boundary Dam Integrated Carbon Capture and Storage project in Estevan\, Saskatchewan\, Canada. Carbon dioxide is captured from the Boundary Dam coal-fired power generation station and transported via underground pipeline to both the Weyburn oil field for EOR\, and to a 3400 m deep injection well at Aquistore. Initial CO2 injection at Aquistore took place in April 2015\, and through August 2023 more than 500\,000 tonnes have been injected. Geology and hydrogeology have played a key role in the entire project using both pre-existing and newly-acquired data. Hydrogeological characterization efforts were divided into four parts: regional hydrogeological and hydrochemical mapping of the site; hydraulic characterization of the storage zone during drilling/testing of the 3400m deep injection and nearby 3400m deep observation well; installation of an extensive shallow groundwater monitoring network; and ongoing hydrogeological and hydrochemical monitoring of the shallow groundwater in the area. All of the geological and hydrogeological characterization results indicate strongly favourable conditions for geological storage at the site: there are no significant faults in the immediate area of the storage site; the regional sealing formation is continuous in the area; the reservoir is not adversely affected by knolls on the surface of the underlying Precambrian crystalline basement; and the shallow groundwater and soil gas horizons do not appear to be hydraulically connected to the deep injection horizons in the subsurface. These results were subsequently used for project planning\, risk assessment\, and permitting of the site; demonstrating the overall storage integrity; and for Measurement\, Monitoring\, and Verification of CO2 storage for regulatory and public assurance. This talk will highlight some of the geology and hydrogeology results from Aquistore and provide an update on a couple of the more interesting outcomes of the project thus far.\n\n  \nEvent Details:\nThursday\, 15 August 2024\nLuncheon: 12 pm for a 12:30 pm start \nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nIncludes a 2-course lunch and drinks \nBookings close 1 pm Monday\, 12th August 2024 \nAny late bookings will incur an additional $20 fee. Strictly no walk-ins.

SUMMARY:PESA SA/NT Branch July Luncheon
DESCRIPTION:Exploration for radioactive waste repositories near urban areas\n\n\n\n\n\n\n\nMarkus Häring\nHäring Consulting \nAbtract\nSave long term storage of nuclear waste is required even in countries without nuclear power plants. Switzerland produces about one third of its power with nuclear energy. The volume of high- medium- and low-level radioactive waste of over sixty years of production is in the same order as toxic heavy metal waste from industry and consumption. Radioactive waste has a precisely determined half-life and can be stored and monitored in controlled containments. In contrast\, heavy metal waste is diffusely distributed\, is not inventoried\, and is of indefinite toxicity.\nNagra\, the Swiss cooperative for the disposal of radioactive waste has explored for a suitable location in various rock formations throughout Switzerland. After forty years of exploration\, a suitable site has been found that is not only geologically safe\, but also meets all political requirements.\nWhen it is possible to find a suitable site for nuclear waste in a country with nine million inhabitants that is smaller than the Eyre Peninsula and on top is located in a tectonically active region\, it should be feasible to find a safe storage location in South Australia. \n  \nEvent Details:\nThursday\, 25th July 2024\nLuncheon: 12 pm for a 12:30 pm start \nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nIncludes a 2-course lunch and drinks \nBookings close 1 pm Monday\, 22nd July 2024 \nAny late bookings will incur an additional $20 fee.

SUMMARY:PESA S/NT Branch June Luncheon on 4 July 2024
DESCRIPTION:Analogues for Subsurface Characterization for the Energy Transition\nProf Simon C. Lang\nCentre for Energy Geoscience\nSchool of Earth Sciences\, University of Western Australia\nsimon.lang@uwa.edu.au\n  \nThe energy transition over the next few decades will provide challenges to all geoscientists who will need to extend the skills and lessons learned from fossil fuel exploration\, development and production to carbon sequestration and utilization (CCUS)\, conventional and H2 gas storage\, sediment-hosted copper\, uranium and lithium exploration\, and related hydrological and geotechnical issues.\nTypically high quality and abundant data is mostly available where existing fields occur (seismic\, wells\, dynamic data)\, but data will be sparser where we need to undertake new geological studies to support the energy transition. To infill the scale-gap between seismic and wells\, all the way down to core and pore-level\, we need to deploy appropriate analogues for the tectonic\, climatic and accommodation/sediment supply regimes.\nThis presentation will focus on depositional systems and their subsurface reservoirs/seals/baffles\, and how analogues from seismic\, well data\, producing fields\, outcrops and modern depositional systems can help constrain the uncertainties involved with subsurface geo-modelling\, that will still be needed to develop the new energy resources needed for the energy transition.\nGeology Matters!\n  \n  \nEvent Details:\nThursday\, 4th July 2024\nLuncheon: 12 pm for a 12:30 pm start \nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nIncludes a 2-course lunch and drinks \nBookings close 1 pm Monday\, 1st July 2024 \nAny late bookings will incur an additional $20 fee.

SUMMARY:GDE Mapping Leading to Play Analysis in the onshore Otway Basin (SA)
DESCRIPTION:GDE Mapping Leading to Play Analysis\nin the onshore Otway Basin (SA)\nChris Cubitt (speaker)  & Paul Strong \nGeological Survey of South Australia\, Department for Energy and Mining \nhttp://www.energymining.sa.gov.au/ \nchris.cubitt@sa.gov.au; paul.strong@sa.gov.au \nThe Otway Basin is a Mesozoic rift basin located in southeastern South Australia and southwestern Victoria\, as well as extending offshore as part of Australia’s Southern Margin. Over 100 petroleum wells have been drilled since the 1890s wells\, and in 1987 Katnook 1 discovered economic gas in the Penola Trough\, with subsequent drilling leading to further discoveries and construction of a processing plant. To date almost 450\,000 barrels oil and 86Bcf of gas have been produced from the basin. \nThe modern Katnook Gas Plant (currently mothballed) has improved the economic viability of small gas discoveries to fuel both local gas markets and electricity generation. The SA Otway Basin is strategically connected to local southeast and statewide natural gas customers by the SEA Gas and SESA pipelines. \nAs part of a larger petroleum systems modelling (PSM) project gross depositional environment (GDE) maps were developed using 7\,965km of interpreted 2D seismic\, interval-specific isopachs with well log motifs\, regional seismic facies analysis and depositional environment (DE) interpretations from 772m of conventional core (23 wells). This mapping interpreted varied depositional systems\, including anoxic\, extensive ice-influenced lacustrine\, lacustrine turbidite\, extensive fluvial/lacustrine\, fluvial/flood plain and growth fault-bound ribbon-like alluvial fan apron environments. GDE maps were produced for the following six key intervals: Casterton Formation\, Lower Sawpit Shale (McEachern)\, Sawpit Sandstone\, Upper Sawpit Shale\, Pretty Hill Sandstone and Laira Formation. \nThe petroleum systems modelling showed for the first time significant oil and gas generation and expulsion in the lightly explored Robe and Tantanoola Troughs\, as well as the Penola Trough. \nPlay analysis has recently been conducted by DEM for all 8 intervals using the GDE mapping and the PSM results\, with the intention of stimulating exploration for hydrocarbons in this region\, including determining areas for a potential acreage release in 2024. The results have been documented on the DEM Energy Resources website under the Geology and Prospectivity \nhttps://www.energymining.sa.gov.au/industry/energy-resources/geology-and-prospectivity/mesozoic-basins/otway-basin  \n  \nEvent Details:\nThursday\,  Thursday 30th May 2024\nLuncheon: 12 pm for a 12:30 pm start \nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nIncludes a 2-course lunch and drinks \nBookings close 1 pm Monday\, 27th May 2024 \nAny late bookings will incur an additional $20 fee.

SUMMARY:PESA SA/NT CHRISTMAS 2023 PESA LUNCHEON DECEMBER
DESCRIPTION:CHRISTMAS 2023 PESA LUNCHEON DECEMBER\nPresented by: Dave Grybowski\, Consultant\nAbstract – \nIf you missed David’s double-header luncheon talk of October last year comprising Cry Me A River and the world premiere of The Project – A Play About Not Working Together\, here’s your second shot at the Christmas Cracker. This December\, PESA SA/NT is paying David $1\,000\,000 to return with another blockbuster. Before dessert\, David will lead a joint discussion on The Books That Hooked Me – an investigation of the childhood books and collectables that turned his head toward geology. Luncheoneers will be invited to share their experience. How can we turn those young brains we babysit into earth scientists and engineers with great Christmas gifts? Specifically\, the challenge of making engineering remotely interesting to a kid compared to all the neat things geological.\nAfter dessert\, there will be a thrilling slideshow on The Role of Toilet Paper. The Chinese invented toilet paper in the 6th Century after discovering gunpowder was much too powerful and what to do with all those books after inventing printing eight centuries earlier? David will show a great variety of toilet paper dispensers with video of how well they don’t work. Naturally\, there will be a tie-up with Christmas at the end\, and remember\, paper beats rock\, any day. \n  \nEvent Details:\nThursday\, December 14th\, 2023\nLuncheon: 12 pm for a 12:30 pm start \nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nIncludes a 3-course lunch and drinks \nTickets: \nStudent Members – $25 \nMembers – $50 \nNon-members – $100 \n  \nBookings close 1 pm Monday\, December 11th.\nAny late bookings will incur an additional $20 fee.

SUMMARY:PESA SA/NT September Technical Luncheon  "Cretaceous depositional environment interpretation of offshore Otway Basin cores and wireline logs"
DESCRIPTION:Cretaceous depositional environment interpretation of offshore Otway Basin cores and wireline logs; application to the generation of basin-scale gross depositional environment maps\nPresented by: Chris Cubitt\nDeputy Director Geoscience & Exploration \nGeoscience and Exploration Branch | Energy Resources Division – DEM \nChris.Cubitt@sa.gov.au \n  \n  \nAbstract\n\nGas production from the Inner Otway Basin commenced in the early 2000s but the deep-water part of this basin remains an exploration frontier. Historically\, the understanding of plays in this region were largely model driven and therefore the ground-truthing of depositional environments (DE) and gross depositional environments (GDE) are critical. This aspect has been investigated for the Sherbrook Supersequence (SS) by the integration of legacy wireline and core data\, with regional 2D seismic facies mapping of new and reprocessed data from Geoscience Australia’s 2020 Otway Basin seismic program. Core observations were matched to wireline logs and seismic facies with resulting well based DE interpretations calibrated to seismic resolution Regional GDE intervals. Integration of well and seismic observations lead to the compilation of a basin-wide Regional GDE map for the Sherbrook SS. This GDE map indicates the distribution of Sherbrook SS play elements such as source rock\, seal and reservoir\, especially across the Deep Water Otway Basin where well data is sparse. \n\n\nEvent Details:\nThursday\,  September 28th\, 2023\nLuncheon: 12 pm for a 12:30 pm start \nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nIncludes a 2-course lunch and drinks \nBookings close 1 pm Monday\, 25th August\nAny late bookings will incur an additional $20 fee.

SUMMARY:PESA SA/NT August Technical Luncheon  "Critical Minerals in SA – The road to net zero"
DESCRIPTION:Critical Minerals in SA – The road to net zero\nPresented by: Bronwyn A Camac (Geological Survey of South Australia)\n\n  \nAbstract \n\nFor about 150 years\, the use of petroleum products has driven world economies and is the greatest influence on quality-of-life improvement.\nBefore then\, we burned whatever we could find\, to keep us warm\, to fuel our emerging technologies\, and to cook our food. But most of these fuels could not keep up with population growth. Our forests were being pillaged\, our health declined due to coal pollution and our oceans stripped of whales.\nOur societies turned to the emerging new fuel – oil and its cleaner partner\, natural gas. We found its value more than just a fuel – we could make things from it – plastic\, clothes\, medicines\, fertilisers\, cosmetics\, and the list goes on and on. So\, dependent upon these products\, it becomes difficult to imagine that we can ever do without them.\nBut that time has come\, just as with wood\, coal and whales\, the market has outgrown us\, demanding cleaner fuels and products which has no effect on the earth and its climate.\nThis single most disruptive event of the last 150 years is being addressed in all countries to drive our economies toward net-zero carbon emission. To support net-zero targets\, the market is moving towards new technologies\, such as electric vehicles\, renewable technologies\, space technology\, telecommunication and defence. All of these technologies need critical minerals.\nThis is space where the mineral resource industry and the energy resource industry collide!\nCritical minerals are described by Geoscience Australia as “minerals that are essential to our modern technologies\, economies and national security\, and whose supply chains are vulnerable to disruption.”\nSouth Australia is well-endowed with many of the minerals and metals projected to be in short supply as this energy transition progresses. SA is rich in copper and currently holds 69% of Australia’s copper resource. It is a major producer of mineral sands\, with their associated rare earth elements and is rich in graphite. A state-wide study is currently underway to uncover SA’s full resource potential\, putting us at the forefront of the world’s energy transformation. \n\n\nEvent Details:\nThursday\,  August 24th\, 2023\nLuncheon: 12 pm for a 12:30 pm start \nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nIncludes a 2-course lunch and drinks \nBookings close 1 pm Monday\, 21st August\nAny late bookings will incur an additional $20 fee.

The trial consisted of eight source tests acquired along two 2D lines\, including: a full-size array (2480 cu.in.) with Sercel G-GUN II in a wide-tow triple source configuration\, eSourceTM (2098 & 1049 cu. in.)\, reduced size (300\, 700 & 1260 cu.in.)\, and Distributed Source tests including Shearwaters Apparition test (140 & 340 cu.in.). A test of a 70 cu.in. airgun was also recorded during a whale mitigation procedure. The aim of the field trial is to investigate whether any of these source options: \n1. Provide the required geophysical data quality \n2. Significantly alter the received anthropogenic sound levels (SPL and SEL) \n3. Changes the impacts on benthic invertebrates via analysis of scallop and lobster specimens placed on the seafloor \nThis combined data will then be used to determine if any of the alternative source options are suitable replacements for conventional full-sized arrays and if any provide a meaningful reduction to potential impact on marine organisms. \nThe study was performed in conjunction with the Institute for Marine & Antarctic Studies\, Fisheries Research & Development Corporation\, Curtin University\, and the Department of Natural Resources & Environment Tasmania. \nScallop and lobster specimens as a model species for crustaceans and molluscs were placed on the seabed below the full array (triple and single source)\, both eSource arrays and one control location. The specimens were assessed over 6 months for physical damage\, chronic effects and survival\, pH\, refractive index\, total and differential haemocyte cell counts\, DNA damage and biochemistry. Lobsters were also assessed for righting ability. The results will not be available until Q4 2023. Noise loggers were collocated with the specimens to measure received sound. \nThe data processing was completed by Shearwater. The results show that all options result in lower S/N raw shot gathers; but also\, that modern processing algorithms are able to compensate for most of this through noise attenuation\, deblending and designature. eSource (2098 and 1049 cu.in.) and the reduced source size options provide very similar final stack and migrated gather quality to the full array. Both apparition tests (140 & 340 cu.in.) were very similar in 2D stack quality but with slightly lower S/N below 4Hz and above 64Hz. The data quality of the other distributed source tests was better in the shallow but worse in the deep due to poor randomisation achieved. There are differences in gather quality that require further investigation. These results demonstrate that alternative sources and/or smaller volumes have the potential to meet survey objectives whilst reducing impact on marine life. \n  \nEvent Details:\nThursday\, July 27th\, 2023 \nLuncheon: 12 pm for a 12:30 pm start \nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nIncludes a 2-course lunch and drinks \nBookings close Tuesday\, 25th July\nAny late bookings will incur an additional $20 fee.

SUMMARY:PESA SA/NT June Technical Luncheon  "A new 3D structural model for the Porgera Region\, PNG Fold Belt: the integration of petroleum and minerals exploration methods"
DESCRIPTION:A new 3D structural model for the Porgera Region\, PNG Fold Belt: the integration of petroleum and minerals exploration methods.\nPresented by: Gareth T. Cooper\, Enigma Energy Services\nWork by: Gareth T. Cooper\, Kevin C. Hill\, Peter Essy\, Mark Haydon & Agnes Pokondepa\n  \nAbstract \n\nThe Porgera Region is a complex strike-slip pull-apart zone located in the central Highlands of PNG. The region sits on the northern margin of fold belt close to the boundary with the Mobile Belt. The region is ~70km NE of the Hides gas field and has been the subject of numerous regional studies by petroleum companies since the early 1970’s. Porgera hosts a gold mine which is one of the richest in the world and lies in a wide valley at an elevation of 2800m surrounded by mountains up to 4000m elevation. The intrusive underlying the Porgera ore-body was emplaced in the earliest Pliocene at the time of maximum compression during orogenesis. \nThe mine has been active for some 30+ years and has been the subject of multiple geological studies over that period. However nearly all studies to date have concentrated on local-scale mapping using methods commonly utilised in the minerals industry. In 2019-2020\, the mine operators\, PJV\, engaged a new study\, this time at a regional-scale and deliberately integrating methods commonly used in the petroleum sector. This included the integration of legacy petroleum data including palynology\, field dips and mapping\, as well as the acquisition of new data including new field transects\, palynology\, pyrolysis-Tmax and the incorporation of these data into thermal modelling and 3D structural modelling software (3D Move). \nThis new regional mapping of the area used high resolution LIDAR in association with field mapping\, analysis of gravity and magnetics data and drilling of 300-500m deep core-holes has allowed development of a detailed 3D structural model. The draft model was used to guide a regional drilling campaign in early 2023 as well as a follow-up sampling program for palynology and pyrolysis. The model also reveals much about previously unknown regional heating events in the Late Cretaceous-Palaeocene as well as the distribution of the Jurassic Om Beds and the Late Cretaceous Chim Formation\, both of which are thermally mature and may have the potential to host deep gas reservoirs. \nThis presentation discusses the methodologies used in the study and the unique integration of minerals and petroleum methods. The resultant model elucidates much about both the Pliocene emplacement of gold-bearing fluids in the area as well as the potential for deep Toro and Chim-aged gas reservoirs within deep structures. \n\n\nEvent Details:\nThursday\,  June 29th\, 2023\nLuncheon: 12 pm for a 12:30 pm start \nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nIncludes a 2-course lunch and drinks \nBookings close 1 pm Monday\, 26th June\nAny late bookings will incur an additional $20 fee.
